It was prepared to help facilities handling chemicals determine, for a specific chemical, whether they may be subject to certain reporting requirements. These lists should be used as a reference tool, not as a definitive source of compliance information. Please refer to the requirements in the appropriate part of the Code of Federal Regulations (CFR).

Introductory material explaining the lists and codes used in the chemical tables,

Appendix B: Radionuclides listed under CERCLA,

Appendix D: TRI chemical categories, or

Appendix E: CERCLA hazardous substance chemical categories.

All appendicies appear in the PDF version of the List of Lists.

Substance Registry Services

EPA’s Substance Registry Services (SRS) database can be used to search for a specific chemical name or Chemical Abstract Service (CAS) registry number. It provides the regulations and statutes applicable to the chemical. Regulatory lists include those managed by EPA and other federal agencies and states. SRS can also be searched by a specific regulatory list and shows all the chemicals on that particular list.
